This paper Graphical user interfaces for computer applications and games are attempted to recreate the study with the exception of testing more mainly focused at providing the user an interface to interact with things, such as number of miss-clicks, distance travelled, graphical components [8]. Doing this usually requires navigating directional changes and time. The keyboard was replaced by a a cursor on a two-dimensional screen and creating some sort of an handheld controller as well. The results were that the mouse event (i.e. clicking/touching), often referred to as a pointing performed best yet again, and proved to be easy to use efficiently device. It’s still possible to navigate with other input devices, such for both new and experienced users. The handheld controller was as a keyboard, but this has been shown to be slow [2, 5]. shown not to be an optimal pointing device, mostly due to it being stuck to a fixed speed and not able to accelerate.

  • The How of Computers
    THE HOW OF COMPUTERS A computer is an electronic device, operating under the control of instructions stored in its own memory, that can accept data, process the data according to specified rules, produce results, and store the results for future use. Data and Information Computers process data into information. Data is a collection of unprocessed items, which can include text, numbers, images, audio, and video. Information conveys meaning and is useful to people. Many daily activities either involve the use of or depend on information from a computer. Computers process several data items to print information in the form of a cash register receipt. A computer processes data into information. In this simplified example, the item ordered, item price, quantity ordered, and amount received all represent data. The computer processes the data to produce the cash register receipt (information). Information Processing Cycle Computers process data (input) into information (output). Computers carry out processes using instructions, which are the steps that tell the computer how to perform a particular task. A collection of related instructions organized for a common purpose is referred to as software. A computer often holds data, information, and instructions in storage for future use. Some people refer to the series of input, process, output, and storage activities as the information processing cycle. Most computers today communicate with other computers. As a result, communications also has become an essential element of the information processing cycle. The Components of a Computer A computer contains many electric, electronic, and mechanical components known as hardware. These components include input devices, output devices, a system unit, storage devices, and communications devices.

  • Play Any PC Game with a Gamepad Using Joytokey for Those Who Prefer Controllers to Keyboards
    Play Any PC Game with a Gamepad Using JoyToKey For those who prefer controllers to keyboards There was a time when “hardcore” PC gamers would look down on the idea of using a gamepad to play PC games. The mouse and keyboard reigned supreme, especially in the golden age of first person shooters. The truth is that joysticks and gamepads have a rich and storied history on the PC, with genres such as racing and flight simulation virtually requiring it to be playable. The problem is that, for a very long time, gamepads on PC were not really standardized. Without a solid idea of what players would be using, many developers simply didn’t bother developing gamepad support for their titles. Now, largely thanks to console ports, the Xbox controller has become the de facto standard for PC gaming too. Better yet, since so many games are also developed for the Xbox, it’s easy for developers to simply include the control scheme. The end result is that if you hook up an Xbox controller to a modern Windows PC, modern games will seamlessly switch over, even changing the in-game UI to reflect gamepad controls. This is the best of time for those of us who love to game with a gamepad on PC, especially from a couch. However, there are thousands of older PC games that only support a keyboard and mouse. Which leaves us with a bit of an issue. Luckily JoyToKey provides an affordable solution. How To Use JoyToKey JoyToKey is a small application sold for a few dollars that takes gamepad input and converts it to mouse and keyboard output.

    INFORMATION SHEET 1.1.5 Storage, Input and Output Devices LEARNING OBJECTIVES: After reading this INFORMATION SHEET, STUDENT(S) MUST be able to: 1. identify the output and input device 2. explain, elaborate and classify the different computer peripherals and its components INTRODUCTION A peripheral is a piece of computer hardware that is added to a computer in order to expand its abilities. The term peripheral is used to describe those devices that are optional in nature, as opposed to hardware that is either demanded or always required in principle. There are all different kinds of peripherals you can add your computer. The main distinction among peripherals is the way they are connected to your computer. They can be connected internally or externally. A computer peripheral is any external device that provides either input or output. Peripherals typically fall into the hardware category and include optional system components. Computer peripherals are add-on hardware to the computer to expand its abilities or improve its performance. By adding memory, computers are able to perform a lot better, or by adding video cards, the computers graphics create more detail. These are just some of the peripherals, although there is a lot more you can put on your PC some of them may not be compatible. Compatibility maybe an issue to some of the peripherals and may even cause the worst outcome –the PC refuses to boot or the PC refuses to recognize the peripheral being added. The easiest way to solve that would be figuring out where it started and you can start from there.

  • Track Ball → It Is Pointing Device That Is Used to Control the Positions Of
    Department Of Computer Application (BBA) Dr. Rakesh Ranjan BCA Sem - 2 Input devices Track ball it is pointing device that is used to control the positions of the cursor on the screen. It is usually used in notebook computers where it is placed on the keyboard . It is nothing but an upside down mouse where the ball rotates in place within a socket. The user can rolls the ball to position the cursor at the appropriate position on the screen and then clicks one of the buttons near the track ball either to select the objects or to position the cursor. The working of a track ball is identical to mouse Touch pad it is small flat rectangular stationary pointing device with a sensitive surface of 1.5 to 2 inch. The user has to slide his or her figure tips across the surface of the pad to point to specific objects on the object. The surface translate the motion and position of the user’s figures to a relative position on the screen The touch pad are widely used in laptop and other handheld devices . The working of the touchpad is similar to that of mouse or a trackball. The pressure of the finger on the surface leads to a capacitance effect, which is detected by the sensors . the sensors send appropriate signals to cpu which interprets them and display the pointer on the screen . Joy stick it is widely used in computer games and computer aided design and manufacturing (CAD/CAM) applications. It has one or more push buttons called switches .

The effectiveness of a second hand, used to hold a touch interface is also considered. Following an investigation into existing research in the domain of touch based user interfaces, an experiment was designed to evaluate the effectiveness of selection, dragging and gesture based input tasks undertaken with both a mouse and using a touch interface. Additionally operation of the touch interface when the device was held in the hand was compared to operation when the touch interface was situated horizontally on a desk, to determine the impact of bimanual operation. The findings suggest that there is little variation in usability between a touch device held in the hand and situated on a desk, but that the touch interface provides an improved experience for an end user over that of a mouse based interface not only for selection as previous researches had indicated, but also for dragging and gesture interaction based input.

  • The Ergonomic Development of Video Game Controllers Raghav Bhardwaj* Department of Design and Technology, United World College of South East Asia, Singapore
    of Ergo al no rn m u ic o s J Bhardwaj, J Ergonomics 2017, 7:4 Journal of Ergonomics DOI: 10.4172/2165-7556.1000209 ISSN: 2165-7556 Research Article Article Open Access The Ergonomic Development of Video Game Controllers Raghav Bhardwaj* Department of Design and Technology, United World College of South East Asia, Singapore Abstract Video game controllers are often the primary input devices when playing video games on a myriad of consoles and systems. Many games are sometimes entirely shaped around a controller which makes the controllers paramount to a user’s gameplay experience. Due to the growth of the gaming industry and, by consequence, an increase in the variety of consumers, there has been an increased emphasis on the development of the ergonomics of modern video game controllers. These controllers now have to cater to a wider range of user anthropometrics and therefore manufacturers have to design their controllers in a manner that meets the anthropometric requirements for most of their potential users. This study aimed to analyse the evolution of video game controller ergonomics due to increased focus on user anthropometric data and to validate the hypothesis that these ergonomics have improved with successive generations of video game hardware. It has analysed and compared the key ergonomic features of the SEGA Genesis, Xbox, Xbox 360, and PS4 controllers to observe trends in their development, covering a range of 25 years of controller development. This study compared the dimensions of the key ergonomic features of the four controllers to ideal anthropometric values that have been standardised for use in other handheld devices such as TV remotes or machinery controls.
